Nearly every large institution now holds a climate ambition of some kind. Most have published one. The harder question, and the one that has occupied a great deal of Dame Alison Rose’s attention since she stepped down from NatWest Group in July 2023, is what happens in the long stretch between the announcement and the deadline, when nothing dramatic is scheduled and the work is mostly unglamorous accounting.

The Distance Between a Pledge and a Plan

A pledge is a statement about a future state. A plan is a statement about the next eighteen months. Rose has argued that the space between those two things is where most corporate climate commitments quietly come apart, because the pledge generates the press coverage while the plan generates the cost. An organisation can carry a 2050 target for a decade without ever encountering a single decision that the target would actually change. Nothing about the pledge forces a confrontation. The deadline is always someone else’s problem, sitting beyond the tenure of whoever announced it.

The correction Rose has pushed for is not more ambition. It is shorter intervals. A target dated 2030 behaves differently inside a company than a target dated 2050, because 2030 falls inside the planning horizon of people who are currently employed and currently accountable.

Why Interim Targets Do the Real Work

Interim targets convert a slogan into a budget line. Once a bank commits to a specific reduction in financed emissions by a specific year, that commitment starts to interact with credit policy and with how relationship managers are compensated. Dame Alison Rose spent three decades watching how targets propagate through a large organisation, and her account of it is fairly unsentimental. A goal that does not eventually change what someone is measured on will not change what that person does.

This is also why interim targets attract more internal resistance than headline ones. They are the point at which the ambition begins to cost something.

The Measurement Problem Underneath All of It

Measuring progress requires a baseline, and baselines in this field remain unstable. A bank calculating its financed emissions depends on data supplied by thousands of client companies, many of which are estimating rather than measuring. Methodologies change. A firm can appear to reduce its footprint substantially in a year when the only thing that changed was the emissions factor applied to a sector.

Dame Alison Rose has been candid that this instability gives institutions an easy way out. If the numbers are contestable, then any inconvenient result can be attributed to methodology rather than to performance. Her position has been that the answer is not to wait for perfect data, since waiting is indistinguishable from inaction, but to publish the methodology alongside the number so that movement can be traced to a cause.

Who Owns the Number

In many organisations, climate metrics live with a sustainability function that has influence without authority. The function reports the number. It does not control the lending decisions that produce the number. Rose has consistently placed ownership further up, arguing that climate performance belongs on the same page as capital and credit quality, reviewed by the same board committee, at the same frequency.

Her experience since leaving NatWest Group, chairing and advising across sectors, has reinforced that view. Where the metric sits determines whether it survives a bad quarter.

What Happens When the Numbers Move the Wrong Way

Any honest measurement regime will eventually produce a result nobody wanted. A portfolio shifts, an acquisition lands, a client base changes, and the trajectory bends upward. Rose has treated this as the moment that reveals whether a company’s climate programme is a management system or a communications exercise. A management system explains the deviation and revises the plan. A communications exercise restates the ambition and changes the chart.

She has noted that institutions willing to report a bad year build more credibility over time than institutions whose numbers only ever improve, because a perfectly monotonic line invites the suspicion that something is being managed other than emissions.

Measurement as a Management Tool

The most useful reframing in Rose’s argument is that emissions data is not primarily a disclosure product for regulators and investors. It is an operating instrument, in the same category as credit loss data. A bank that knows precisely which parts of its book carry transition risk can price that risk and allocate capital accordingly. A bank that only knows its aggregate figure to two decimal places for the annual report has bought a compliance artefact rather than a capability.

Where the Discipline Comes From

None of this depends on believing anything particular about climate policy. It depends on a much older institutional habit, which is that organisations improve what they count and neglect what they estimate. Rose’s contribution to the debate has been to keep dragging it away from ambition, where everyone agrees, and back toward measurement, where the disagreements are real and the progress actually happens.
