Jonathan Gardiner is a native speaker of English and has good knowledge of German, Spanish, and French.

In his work at the Ecologic Institute, Jonathan Gardiner conducts research on the effectiveness of policies and policy mixes for achieving climate neutrality. He is currently involved in several EU-funded projects on carbon pricing, including the Further Development of Emissions Trading after 2030, which examines the potential extension of emissions trading to agriculture and the integration of carbon removals. He is also working on a project exploring potential carbon pricing designs to cover oil extraction. He also contributes to the European Climate Neutrality Observatory, where he assesses the state of carbon dioxide removals across the EU. In addition, he is developing a Strategy for the Financing of Permanent Carbon Removals at the EU level.

Previously, Jonathan Gardiner researched and managed "Transformative Policies for a Climate-Neutral European Union (4I-TRACTION)", where he researched fossil fuel phase-out policies and carried out a quantitative analysis of EU public procurement. He also contributed to both the ESABCC's 2025 report on scaling up carbon removals and the World Bank State and Trends of Carbon Pricing 2023 report. Jonathan Gardiner is also engaged in capacity building activities on emissions trading, covering the design and implementation of emissions trading systems in emerging economies and developing countries. In August 2022, Jonathan organized and assisted with moderation at the ICAP Summer School on Emissions Trading in Florence (Italy).
