ENVIRONMENTAL IMPACT REPORT

![]()

2025 marks a year of structural change for Christie’s Sustainability Programme, as we strengthened the foundations needed to underpin long-term progress.
With the addition of Gooding Christie’s to support our newest sale category, Automobiles, we took the decision to reset the boundary of our reporting and established a new greenhouse gas (GHG) emissions baseline. The inclusion of Gooding Christie’s into our previous calculations had no material impact on our emissions (less than 5%). At the same time, we enhanced our carbon accounting methodology to reflect improved data quality and align more closely with evolving best practice. Together, these changes provide a more complete and accurate view of our carbon footprint, particularly across our value chain.
Against this backdrop, our reported emissions have increased from 2024 by 16%. Most of this increase is due to a planned and needed refurbishment of our Rockefeller Centre space in New York which began in 2025 and accounts for 19.5% of our overall carbon footprint. This project, which includes investments in infrastructure (such as LED lighting and cooling chillers), will improve our emissions in the long term but will also affect our data for 2026 and 2027. We will always need to make deliberate, time-bound capital investment across our estate and operations and take these opportunities to improve the efficiency within our buildings to support long-term resilience. Emissions overall for 2025 have decreased by 39% set against our baseline year of 2019 and our commitment to our goals for 2030 remain. We recognise that progress is not always linear, and periods of investment and transition can lead to short-term increases as we build for the future.
Importantly, the commitment to our Science Based Targets initiative (SBTi) targets remains unchanged. Across logistics, travel, energy use, and supplier engagement, we continue to integrate emissions reduction into day-to-day decision-making. At the same time, we are operating in a complex external environment, shaped by economic uncertainty, geopolitical pressures, and ongoing disruption across global markets. These factors can influence both the pace and delivery of change, but they do not alter our direction.
Looking ahead, our focus is to continue a downward emissions trajectory. This will be supported by more precise measurement, deeper collaboration with our suppliers and partners, and targeted investment where it can deliver the greatest impact. We will continue to report transparently on both progress and setbacks, and to champion collective action across the art world, supporting more

This report presents Christie’s environmental performance for 2025, covering business activities and supply-chain categories within our defined reporting boundary. It provides an overview of our progress toward long-term emissions reduction goals, alongside continued improvements in the quality, scope, and accuracy of our environmental data.
The structure of the report remains consistent with previous years, setting out progress against our Science Based Targets initiative (SBTi) commitments and detailing actions across six key operational areas: Shipping, Travel, Buildings, Procurement, IT, and Publishing.
The report also explains updates made during the year to our greenhouse gas (GHG) emissions inventory, including emissions recalculations linked to the acquisition of Gooding Christie’s and refinements to our accounting methodology. These changes have resulted in restatements where applicable and are intended to provide a more accurate and representative view of Christie’s environmental footprint as the organisation evolves.
The last section of the report, Sustainability Advocacy, provides more information regarding our sustainability work beyond impact management, including our charitable activities.
Together, this report reflects both performance and progress in reporting maturity—capturing emissions reduction outcomes alongside our ongoing efforts to strengthen transparency, consistency, and credibility in environmental measurement and disclosure.

Our ambition
Christie’s sustainability strategy is guided by three goals - zeroimpact, nature stewardship, and collective action — which shape our approach to reducing environmental impact across our operations and value chain. We pledge to report our progress through three pillars of Commit, Communicate, and Collaborate.
Christie’s is committed to delivering meaningful and measurable emissions reductions across its operations and value chain.
Christie’s continues to operate in line with our GHG emissions reduction targets, which were validated in 2024 by the Science Based Targets initiative (SBTi). These targets define our pathway towards Net Zero and guide our actions across all areas of the business.
We are committed to reducing absolute scope 1, 2, and 3 greenhouse gas (GHG) emissions by 50% by 2030 from a 2019 base year including:
• Reducing 90% of absolute scope 1 and 2 emissions by 2030
• Reducing 46% of absolute scope 3 emissions by 2030
Under our long-term (Net Zero) target, we aim to reduce 90% of absolute scope 1, 2, and 3 GHG emissions by 2050 from a 2019 base year.

Transparent and consistent reporting underpins our approach to sustainability.
This report represents the sixth year of Christie’s environmental reporting and reflects our ongoing commitment to transparency and accountability.
Following the acquisition of Gooding Christie’s, we were required to recalculate our emissions to reflect this expansion. At the same time, we introduced updates to our methodology to improve data accuracy and to ensure we remain consistent. The updates include, but are not limited to:
• Expanding the number of our top suppliers for GHG emission scanning from 30 to 50
• Validating suppliers’ methodologies for activity-based GHG emissions and reverting to using industry average where necessary
• Using employee commuting survey results to estimate emissions based on more accurate commuting patterns
As a result, previously reported figures for 2019 – our base year – and 2024 –the immediate previous year (for comparison purpose) – have been restated. These updates will help us make better data comparisons over time and ensure alignment with evolving best practices in emissions reporting.

Strengthening partnerships with suppliers, clients, peers, and art institutions to support collective action and advance sustainability in the art sector.
Christie’s continues to work with suppliers, clients, and industry peers to drive progress towards shared sustainability goals.
In 2025, we built on existing partnerships across key areas such as logistics, packaging, and IT, with a continued focus on improving data quality, increasing transparency, and supporting the adoption of lower-carbon practices across our value chain.
Highlights include our continued support and active membership of the Gallery Climate Coalition (GCC), including co-sponsorship with Hauser and Wirth of their first Stocktake Report, ongoing investment in reusable crating solutions, and the third year of our Sustainable Shipping Standard programme with logistics suppliers.
We also remain actively engaged in industry dialogue and collaboration, recognising the importance of collective action in addressing environmental challenges across the art sector. As an example of our contribution, we hosted the launch of London’s inaugural Art + Climate Week in November 2025.

In 2025, total emissions within Christie’s reporting boundary amounted to 48,262 tCO₂e. This represents a 16% increase compared with 2024, whilst remaining 39% below our 2019 baseline.
Previous disclosures indicated that we had outperformed our 2030 emissions targets. However, enhancements to our GHG emissions accounting methodology, combined with the inclusion of emissions from Gooding Christie’s, have materially revised this position.
• The Gooding & Company acquisition (now Gooding Christie’s) added 1,604 tCO2e to 2019 base year and 1,573 tCO2e to 2024. This was less than 4% of the overall carbon footprint.
• In parallel, methodological improvements, driven by higher-quality data and more comprehensive coverage resulted in a 5% decrease from the base year 2019 and 62% increase in 2024, compared to previously reported figures excluding the Gooding Christie’s addition. This change is mainly driven by the improvement in the accuracy of the data we now have for measuring our emissions related to procurement with our suppliers (this is explained in the ‘Procurement’ section below).
While these refinements have led to changes in reported performance, they strengthen the credibility of our disclosures and improve our ability to manage emissions over time.
As a growth-oriented business, including through acquisitions and expansion, changes in organisational boundary are expected and are reflected transparently in our reporting.
The chart below presents Christie’s’ GHG emissions within our updated SBTi target boundary1 across six main operational areas, from the 2019 base year.
Note: We did not recalculate GHG emissions from 2020 to 2023 as this period is no longer necessary for our management nor representative of our usual business activities. The data from these years is therefore not included throughout this report. Investment is an immaterial emission source, therefore, is included in our footprint but not analysed in the next section.
The emissions increase in 2025 was primarily driven by a significant rise in procurement-related emissions, which increased by 44% from 2024 and accounted for 54% of the total emissions in 2025. This increase reflects two reinforcing factors:
Procurement emissions in 2025 were significantly influenced by constructionrelated expenditure associated with a milestone renovation of our headquarters at Rockefeller Center in New York. Emissions within the Construction category increased from 919 tCO₂e in 2024 to 10,088 tCO₂e in 2025, making Construction the single largest contributor to the year-on-year increase.
Capital goods and construction are inherently emissions-intensive, and this investment therefore had a disproportionate impact on total reported emissions. This activity is expected to be largely non-recurring after 2027 and is not anticipated to represent a sustained source of emissions at a similar scale.
In parallel, we strengthened our procurement emissions methodology by expanding the coverage of supplier emissions assessment and applying more rigorous data quality criteria. As a result, a greater number of suppliers were assessed, although a smaller proportion of supplier-specific data met the criteria for use. This led to the application of more conservative industry-average emission factors where necessary to maintain consistency and alignment with broader decarbonisation pathways.
These enhancements have improved the robustness and accuracy of supplier-related emissions accounting, albeit with a corresponding increase in reported procurement emissions. Where primary supplier data was available— such as for cloud service providers—it was prioritised, improving the accuracy of estimations and enabling more meaningful differentiation across categories.
By emissions scope, Scope 3 indirect emissions continue to represent the largest share of Christie’s total carbon footprint. Emissions within our direct operational control—Scopes 1 and 2—accounted for 2% of total emissions in 2025.
• Scope 1 and 2 emissions increased marginally by 2% compared to 2024, while remaining 81% below the 2019 baseline. This sustained reduction reflects continued investment in renewable energy procurement across our sites and ongoing energy efficiency improvements.
• Scope 3 emissions increased by 16% compared to 2024, mainly driven by procurement activity associated with the New York renovation project. Despite this increase, Scope 3 emissions remain 35% below 2019 levels. Following the completion of this project in 2027, we expect emissions to resume a downward trajectory, supporting our aim to achieve a 46% reduction by 2030.
While Procurement drove the overall increase, other areas show continued progress or stability. From 2024:
• Buildings emissions increased by 4% to 3,151 tCO2e (7% of total emissions)
• Travel emissions decreased by 16% to 5,157 tCO2e (11% of total emissions)
• Shipping emissions decreased by 1% to 8,272 tCO2e (17% of the total emissions)
• IT emissions decreased by 5% to 5,128 tCO2e (11% of total emissions)
• Publishing emissions decreased by 40% to 299 tCO2e (less than 1% of total emissions)
Overall, these results highlight the structural importance of value chain emissions to Christie’s footprint, while demonstrating that targeted operational actions continue to deliver reductions across several key areas.
Building emissions constitute:
• Energy: direct emissions from the consumption of natural gas, other fuels, and refrigerants (scope 1); indirect emissions from the generation of the electricity we purchase (scope 2).
• Others: scope 3 emissions from employee commuting, from the paper we purchase for our buildings, and from the disposal and treatment of waste and water waste generated in buildings.
In 2025, building emissions increased by 4% from 2024 but reduced by 62% from 2019 level.
The overall increase in building emissions was primarily driven by structural changes in business activity. The acquisition of Gooding Christie’s resulted in a greater number of off-site sales, leading to higher estimated energy consumption and associated emissions. In addition, emissions from natural gas and refrigerants increased by 19%, largely due to the construction project in New York.
Electricity, heat and steam emissions across our operating sites decreased by 12%. We credit this achievement to the cumulative impact of efficiency improvements, operational changes and ongoing management of the global property portfolio. We also achieved full coverage of electricity consumption at all sites with renewable energy and intend to maintain this level going forward.
In 2025, Christie’s continued to implement targeted measures to improve operational efficiency and reduce environmental impact:
• Ongoing energy audits to identify efficiency opportunities.
• Improvements in recycling and waste management practices, contributing to a 5% reduction in waste treatment emissions year-on-year.
• Maintenance of 100% renewable electricity coverage through a combination of direct procurement and renewable energy certificates (RECs).

Business Travel emissions constitute:
• Air travel: staff travelling to visit clients, undertake valuations, attend auctions and events, or meet with colleagues.
• Other types of travel: staff travelling in company cars or in personal cars used for business trips, as well as by train, public transport, etc.
Business Travel Emissions Overview 2019–2025 (in tCO2e)
In 2025, business travel emissions decreased by 16% compared with 2024 and by 67% against the 2019 base year.
Overall travel activity remained broadly stable following the post-pandemic rebound; however, reductions in the average emissions intensity of air travel contributed to the year-on-year decrease.
Air travel continues to be the dominant driver of travel-related emissions, accounting for 94% of the total in this category.
Christie’s continued to apply its Travel Policy and strengthened communication on the environmental impact of travel, supporting greater awareness, transparency, and accountability in decision-making. This has contributed to a gradual shift towards lower-carbon travel options, including:
• An increase in international rail travel compared to 2024
• Greater use of public transport, including subways and ferries
• Reduced reliance on higher-emissions modes, including fewer company cars and lower taxi usage
Overall, the data indicates a sustained moderation in travel-related emissions, driven by both policy implementation and behaviour change.

Shipping emissions constitute:
• Freight: of artwork for internal logistics between Christie’s sites before the sale (i.e., from the seller to the auction room) or after the sale (i.e., shipping organised on behalf of the buyer). Tours are also included in our data.
• Packaging and storage: indirect emissions from the production of packaging materials (e.g., crates) and from outsourced storage.
In 2025, shipping emissions decreased by 1% from 2024 and by 62% from 2019 base year.
The year-on-year reduction was primarily driven by lower distribution emissions, the largest contributor to this category, which decreased by 14% from 2024. This was supported by a reduction in the emissions intensity of airfreight, reflecting updated emissions factors.
Packaging emissions increased by 42% during the year, driven primarily by higher material volumes. However, this increase should be treated with low confidence, as it is based on a limited dataset. Improving the quality of our data for this area remains a key priority.
In 2025, Christie’s continued to advance targeted initiatives to reduce shippingrelated emissions and improve supply chain performance:
• Continued implementation of the Sustainable Shipping Standard programme, supporting small and medium-sized suppliers in developing sustainability capabilities aligned to Christie’s framework.
• Expansion of reusable packaging solutions, including broader deployment of EarthCrate and RokBox2, alongside sharing best practice across the industry. Data of reusable crates is also captured and used for packaging emissions estimation.
• Ongoing supplier engagement, including through the Extended Producer Responsibility (EPR) compliance processes, to improve data quality and enhance understanding of packaging end-of-life impacts.
• Progress towards the phase-out of polystyrene and bubble wrap in Europe, in collaboration with suppliers.
• Continued promotion of lower-carbon transport options, especially the use of sea freight for wine shipments and a twice-yearly container service from New York to Hong Kong, as a practical and scalable alternative to air transport.

Procurement emissions constitute:
• Purchased Goods & Services: The emissions from the extraction, production, and transportation of goods and services purchased by the company, not included in capital goods.
• Capital Goods: The emissions from the extraction, production, and transportation of capital goods (CAPEX) purchased by the company.
Estimating emissions across a diverse range of purchased goods and services remains complex. In 2025, we strengthened our procurement emissions accounting methodology by increasing the use of high-quality supplier-specific data, complemented by industry-average emissions estimates where necessary. When we know where the emissions sit – where the hotspots are – by having better data, we can make more informed decisions and adapt. In the area of procurement, we are reliant on data from our suppliers.
We expanded our assessment of publicly available upstream emissions data from 30 last year to the top 50 suppliers across our top 5 high-spend categories, including IT, and applied more stringent quality criteria to determine suitability for emissions accounting. Where supplier-specific data did not meet these standards, conservative industry-average factors were applied to ensure consistency and alignment with broader industry decarbonisation trajectories.
Note: As we revised the emissions accounting methodology for Procurement, top 4 represents emissions from the top 4 categories with the highest spends, excluding IT procurement.
Better measurement tools available in 2025 have resulted in a significant restatement for our emissions for 2024, particularly as most of top 30 supplier data was from IT suppliers. These restated emissions more accurately reflect our footprint across our supplier base.
Procurement emissions were also influenced by a 14% increase in expenditure, largely driven by our milestone capital project at Rockefeller Center as well as the acquisition of Gooding Christie’s. The acquisition contributed approximately 3-4% to the total procurement emissions across 2024 and 2025.
Christie’s has put in place emission reduction plans with key suppliers and across our high-spend categories. Insights from these plans are informing the continued evolution of our sustainable procurement strategy, enhancing data quality and transparency, make our suppliers more accountable, and enabling more targeted and effective supply-chain decarbonisation. IT, for example, is now managed as a distinct priority category, reflecting both its scale and emissions intensity.

IT emissions constitute:
• IT Procurement: the indirect emissions from our software and hardware purchases, as well as the services needed to upkeep and monitor them.
• Data centres: the emissions from running our two data centres.
• Post and Telecommunications: the emissions from our procured postal and telecommunications goods and services.
• E-Waste: the emissions from end-of-life treatments of our electrical and electronic equipment.
• On-blockchain activities: including but not exclusively the emissions associated with NFT-related transactions and Christie’s 3.0.
The reduction in reported IT emissions for the 2019 baseline reflects improvements in the data quality, driven by expanded assessment of supplier GHG data and better representation of emissions across this category.
In 2025, IT emissions decreased by 5% compared to 2024, although they remain 33% above 2019 levels. This increase reflects sustained investment in digital capabilities to support business growth and transformation, particularly following the Covid-19 period.
At the same time, emissions reduction across the IT value chain remains challenging. Many suppliers are managing rising energy demand associated with scaling cloud infrastructure, computing power, and connectivity—factors linked to the continued growth of digital services.
This year, Christie’s continued to strengthen the management of IT-related emissions through targeted actions:
• Ongoing IT supplier engagement to improve data quality and transparency, particularly across software, hardware, and associated services, which remain the largest emissions sources within IT. In 2025, we added three more companies to our IT supplier engagement programme.
• Increased use of activity-based emissions data from key suppliers, improving the accuracy of cloud-related emissions accounting.
• Progress in optimising data centre operations, including transitioning to more energy-efficient facilities and reducing the number of racks. Supplier actions on renewable energy procurement contributed to a significant reduction in data centre emissions compared to 2019.
• Continued collaboration with e-waste partners to minimise equipment sent for end-of-life treatment, maintaining close-to-zero e-waste emissions.

Publishing emissions constitute:
• Printing: of the material we use in support of our sales (mainly auction catalogues), including indirect emissions from paper, other materials, and printing.
• Distribution: sending printed material by air or other transport types.
• Packaging: the packaging used for the distribution of sales materials.
In 2025, publishing emissions decreased by 40% compared to 2024 and are now 94% below the 2019 baseline. This sustained reduction reflects the continued application of our publishing policy, which prioritises digital formats and critically evaluates the need for printed materials, resulting in lower print volumes and reduced distribution requirements.
As part of improving data coverage, we have begun tracking emissions associated with packaging used in the distribution of sales materials. Applied retrospectively, these emissions add approximately 104 tCO₂e to the 2019 baseline, representing an immaterial contribution (0.1%) to Christie’s total emissions. This improved visibility supports more informed decision-making and enables further optimisation of packaging materials over time.
Publishing emissions now account for less than 1% of Christie’s total footprint, reflecting the structural shift towards more efficient and lower-impact practices across this category.
In 2025, Christie’s continued to implement targeted actions to reduce emissions associated with publishing:
• Ongoing reduction in print activity, contributing to a 30% decrease in printing-related emissions compared to 2024
• Continued prioritisation of lower-carbon transport modes for distribution, including a shift from air to road freight where feasible; air freight volumes declined while road freight remained stable
• Additional reductions supported by lower emissions intensity factors for air freight

Guided by our belief that lasting sustainability progress in the art world requires knowledge-sharing, collaboration, and action, we continue to engage actively across the sector. Through our Communicate and Collaborate pledge, we contribute to open industry dialogue, sharing insights from our own journey and encouraging collective progress across the art ecosystem. The publication of our annual report – this being our 6th – is part of this commitment.
In 2025, Christie’s participated in a range of forums, conferences, and events focused on advancing dialogue on climate action, ethics, and sustainable practice within the art sector and beyond. As an active member of the Gallery Climate Coalition (GCC), we continued to support sector wide collaboration aimed at reducing the environmental impact of the visual arts.
In November, as part of London’s inaugural Art + Climate Week and alongside the UN climate conference (COP) in Brazil, Christie’s partnered with the GCC to host an exclusive preview of the GCC Stocktake Report: A Five Year Review of Climate Action in the Visual Arts at our London headquarters. This landmark publication, co-sponsored by Christie’s and Hauser & Wirth, represents the first international, sector wide assessment of climate action in the visual arts, capturing progress made since the GCC’s inception while outlining remaining challenges and opportunities for further action.
The event brought together voices from across the art world for discussion and knowledge sharing on how creativity, collaboration, and behavioural change can drive systemic progress toward a more sustainable future. Contributors to the report, including the GCC Chair, shared insights on advances to date and the role of collective action in accelerating change across the sector.
Alongside the report preview, Christie’s hosted an industry showcase with partners including RokBox, Crown Worldwide Group, and Crozier Fine Arts, highlighting innovative approaches to reducing carbon emissions and waste across art shipping, logistics, and collections management.
Through these engagements and others, we aim to support a more informed and practical conversation about sustainability—sharing perspectives on what is changing, where barriers remain, and how collaboration across the art ecosystem can help deliver lasting progress.
In August 2025, Christie’s Inside Job auction in New York showcased a curated selection of works created by our colleagues across roles and disciplines, offering accessible entry points for new collectors alongside pieces for seasoned buyers. Buyer’s premium proceeds were donated to support Endangered Rainforest Rescue, with funds directed to protecting and restoring the Darién Gap that lies between Central and South America.
This Christie’s Environmental Impact Report has been prepared by Christie’s in association with Accenture. It provides a detailed account of our greenhouse gas (GHG) emissions arising from our operations and relevant value chain activities within the reporting boundary and covers performance of the 2019 base year, the previous year 2024, and the recent year 2025.
In 2025, we updated our reporting basis to reflect the acquisition of Gooding Christie’s and introduced methodological improvements to enhance data accuracy, consistency, and completeness. Where appropriate, prior-year figures have therefore been restated to support like-for-like comparability over time. The carbon footprint has been compiled using operational and procurement datasets, supported by interviews with key personnel to interpret and categorise activity data. Where primary data was not available, emissions were estimated using modelling approaches developed for Christie’s and aligned with best practice in GHG accounting.
All data collected and analysed for this report follows the World Resources Institute (WRI) GHG Protocol principles of relevance, completeness, consistency, transparency, and accuracy. We continue to strengthen our approach to data collection and calculation in line with evolving best practice to ensure our reporting remains robust and useful for stakeholders.
