The TfL Pension Fund has beaten its 2030 emissions reduction target five years ahead of schedule, while warning that further progress is likely to be more uneven.
As of March 2025, the fund had cut its carbon footprint by 58% against a 2016 baseline, exceeding its emissions target well ahead of plan.
TfL, a defined benefit pension fund with a defined contribution tranche, manages the retirement savings of Transport for London staff. Unlike most UK DB schemes, it remains open to further accrual. Over the past decade, the fund has not only expanded its ESG investments, which now account for 16% of the portfolio, but has also more than doubled assets under management from £7bn to £14bn, according to its latest sustainable investment report.
However, the fund acknowledged that much of the emissions progress to date has been driven by external factors rather than real-world reductions at portfolio companies. The relative decline of oil and gas holdings alongside the rising weight of technology firms has accounted for a significant share of the improvement.
"We have continued to identify and invest in attractive sustainable opportunities, a process made easier as overexuberance gave way to realism, sound ideas, and improved risk-adjusted returns. There has never been a better time to deploy long-term pension capital for both attractive returns and a strong sustainability impact" said Padmesh Shukla, CIO for the TfL DB and DC plan.
With many of the easier gains now achieved, the fund cautioned that future emissions reductions are unlikely to follow a linear path. It cited the growing energy demands of AI and the increasing importance of emerging markets as key challenges in the next phase of its strategy.
Despite this, TfL remains committed to increasing allocations to emerging markets, arguing that they are essential for long-term returns and portfolio diversification. Among other initiatives, the fund has committed £100mn to an emerging market equity strategy managed by the International Finance Corporation, targeting commercially viable investments with significant ESG impact.
