Sprite declares a large card, then supplies a 477px logo
twitter:card is summary_large_image. The image is en_sprite_logo_green-text-only_477x180.png.

So the large card renders a small logo
Upscaled, letterboxed, or both, depending on where it's pasted.

What's actually wrong
The Sprite brand page asks for the large-format card and then hands it a 477x180 logo. The slot wants roughly 1200x630 at 1.91:1; this asset is 2.65:1 and a fraction of the required width, so platforms either upscale it into softness or pad it into a letterbox. Meanwhile the sustainability section ships no og:image at all, so one property is running two different failure modes at once.
This is cause 4 of the 5 ways link previews break. The full breakdown covers the manual fix and the automatic one.

Rendered at the exact dimensions each platform asks for. Same logo, right context.

Two failure modes on one property
A wrong-shaped image on the brand pages, no image at all on sustainability.

For whoever owns the templates
The card type is a promise
Declaring summary_large_image commits you to filling a 1.91:1 frame. A 477x180 logo can't, so the platform improvises.

og:image: 477x180Logos aren't share images
Logo files are built for headers and favicons: transparent, small, wrong aspect. Reusing them in the share slot is the most common CPG mistake.
Right size, every platform
OpenGraph+ renders per consumer, so X, Facebook, LinkedIn, and iMessage each get an image at the dimensions they actually want.
